Redirect to a unique https URL (purchased certificate)

Hello,

We have many domains on a zimbra server (zcs-NETWORK-5.0.1_GA_1902.RHEL5) which access the webmail with webmail.domain1.com webmail.domain2.com ...

We want to force https (using zmtlsctl redirect) and to redirect to a uniqu URL which has a valid certificate (to prevent to get the "wrong name warning" about the certificate for our customers) : https://mail1.ourdomain.com
